ᐅ What is a reasonable cost for a new gas boiler?

@kati1337 your post about heat pumps focused purely on financial aspects—what you pay, etc. It’s good that you’re trying to keep your carbon footprint small. Respect for giving up cruises. I don’t do cruises either, but I wouldn’t give them up if they were very important to me.
Is your old car broken? Or are you planning to switch from a still functional car to an electric vehicle? That wouldn’t make much environmental sense.
At 2000 km/year (1200 miles/year), you could probably just use taxis :p

We’re getting off topic 😀 But no, it’s not exactly broken. We currently have two small gasoline cars but don’t need two anymore. We plan to sell both in the midterm and buy an electric vehicle. Right now it’s really uneconomical because we drive so little. Soon we’re moving closer to family, so the 550km (340 miles) trips will disappear as well. However, we will need to replace vehicles eventually because our family car is currently an Audi A1, and my husband drives a Smart. The family car is too small now, we hardly ever need the Smart, but we also need an automatic transmission because my husband can’t or isn’t allowed to drive a manual. An electric vehicle simply makes sense in this case.

I can understand the topic shift from gas heating to heat pump heating, but what do children, housebuilding as a whole, cruises, and cars have to do with it?

The claim that gas is generally better than a heat pump for large houses lacks any logic.

Simply calculate the costs for purchase and consumption of each heating type objectively, and if they are (as expected) close to each other, choose the environmentally friendly technology.

In other words, you are advocating for the "decimation of humanity" (by whatever means) and barrack-style housing. Maybe you should consider going into politics?!
By the way, your last paragraph is simply a lie and—as always—not supported by any data.

Your heat pump consumes energy. The construction of your house required a lot of energy and resources. So it can never be fully offset.
If you want to read up on children and their impact, try searching Google for birthstrike.
A child currently produces about 58 tons (about 64 short tons) of CO2 emissions per year over their lifetime—roughly ten times more than a car emits per year.

To clarify once more: I acknowledge everyone’s right to family planning and I do not intend to influence anyone’s decisions in any way.
The question is simply where to start. Usually with factors that have a significant impact, not those that account for 0.0000x%.
As harsh as it sounds, those without children are actually the “environmentalists.”
However, childlessness is certainly not a choice made for this reason alone.

A child currently causes about 58 tons (63.9 tons) of CO2 emissions per year over their entire life. That’s about 10 times more than a car per year.

The question is where to start. Usually with the things that have the biggest impact, not those that account for 0.0000x%.
As harsh as it sounds, people without children are actually the “environmentally friendly” ones.
Child-free people are certainly not child-free for this reason alone.

If we all give up having children, then we could go back to installing gas boilers and oil heating systems, because we wouldn’t have anyone left to preserve the climate for. The Earth doesn’t really care. A few million years after we’re gone, the planet will be fine again.

The idea that gas is generally better than a heat pump for large houses is unfortunately not logical.

Just objectively calculate the purchase and running costs for each heating type, and if they (as expected) are close, then by all means choose the more environmentally friendly technology.

I think we have different definitions of “large” houses.
I’m talking about houses of 500 m2 (5,380 sq ft) or more (large single-family and multi-family homes).
Why isn’t a heat pump that practical there? It actually makes sense: Because higher supply temperatures are required due to power losses. This reduces efficiency. Also, a large peak capacity is needed, for example, when everyone is showering in the morning…
